The Broncos final preseason practice is history. The team spent more than two hours Wednesday morning preparing for Thursday’s fourth preseason game at Arizona.

The team will travel to Phoenix later Wednesday afternoon.

The Broncos will reduce their roster from 75 to 53 on Friday after turning from Arizona, and will hold their first regular-season practice on Monday.

For now, the backups got heavy work in the final preseason practice, and those second- and third-stringers expect to see the most playing time against the Cardinals while starters like Peyton Manning sit.

Coach John Fox declined to name a specific quarterback rotation for Thursday’s game, but it is expected that Caleb Hanie will start, followed by rookie Brock Osweiler, who is returning to the metro area where he spent three years playing college football.

“This is really my last opportunity to go out there and show the team, the coaches what I can do in a game opportunity,” Osweiler said. “I’m looking forward to it.”

The Broncos had 73 of their 75 players participate in practice. The only two players held out were guard Tony Hills (neck) and guard Chris Kuper (forearm).
